UNITED STATS PTEN, OFFICE JACOB IITOLFSON, OF BROOKLYN, NEW YORK, AND DOROTHY LANGIDON POTTER, OF HAOKENSACK, NEW'J'ERSEY, ASSIGNORS TO NATIONAL OIL PRODUCTS COMPANY, OF

HARRISON, NEW JERSEY, A CORPORATION OF NEW JERSEY PROCESS FOR THE TREATMENT OF TEXTILE FIBERS Ilo Drawing. Application filed July 31,

. Our invention relates to a process for the treatment of textile fibers and relates particularly to a process adapted for the treatment of silk.

' In'the preparation of silk it is essential that the waxes and be softened and that it be converted into a soft, pliable condition and for certain uses, as for hosiery tram, it is desirable that the silk be hygro- 1 scopic in order that it may be knitted direct from the cone without the necessity of back winding, which requires an additional softening treatment.

This softening of the silk fiber and gum has usually been accomplished by immersing the fiber in a bath of water and emulsified oil for about 12 hours, removing and whizscopic and can be knit wtihout back winding.

Zing. This process allows a large amount of oil to remain in the bath, thus causing a loss thereof, the fibers are not uniformly pene- 'trated and are not hygroscopic. Attempts.

The process of our invention comprises introducing an aromatic hydroxy compound,

a salt of a sulpho acid of an aromatic hydroxy compound or a derivation thereof into the treatment bath, among which are a salt of'beta naphthol 3 :6 disulpho acid (R acid), a salt of beta naphthol 6 monosulpho acid (Schaflers acid), a salt of alpha naphthol 4 monosulpho acid (N. W. acid), a salt of sulphonated cresol.

We give the following as one example of our process: I

An emulsion is made of 14 pounds soluble olive oil (sulphonated olive oil) and 4.0 gal- Ions of water.

1929. Serial No. 382,582.

' 2 pounds of R salt are dissolved in 40 gallons of water.

The emulsion is added to, and thorougly mixed with, the solution of R salt and 100 pounds of silk are immersed therein for 12 hours, removed and whizzed.

By our process practically, all of the soluble oil is absorbed by. thejsilk from the bath, whereas in the present employed process about 18 pounds of oil would be emplo ed, only about 20 percent of which is absor ed, the remainder being wasted.

In addition to .this economic advantage, our process produced better and more even penetration and makes the silk hygroscopic, all of which qualities are of the greatest advantage in the further treatment of the fiber.

By aromatic hydroxy compounds in our claims we mean the aromatic hydroxy compounds themselves, their salts, their sulpho acids and derivations, whether used singly or in combination with each other.

We do not limit ourselves to the particular chemicals, time of treatment, or steps of procedure specifically mentioned, as these are given simply as a means for describing the process of our invention.

What we claim is 1. In the treatment of textile fibers, the step which comprises treating the fiber with a soluble oil and an aqueous soluble salt of beta naphthol 3: 6 disulpho acid.

2. In the treatment of textile fibers, the step which comprises treating the fiber with soluble olive oil and an aqueous soluble salt of beta naphthol 3:6 disulpho acid.

3. In the treatment of silk, the step which comprises treating the fiber with a soluble oil and an aqueous soluble salt of beta naphthol 3:6 disulpho acid.

4. In the treatment of silk, the step which comprises treating the fiber with soluble olive oil and an aqueous soluble salt of beta naphthol 3 6 disulpho acid.

5. In the treatment of textile fibers, the step which comprises treating the fiber with a soluble mineral oil and an aqueous soluble salt of beta naphthol 3 :6 disulpho acid.

6. In the treatment of silk, the step which comprises treating the fiber with a soluble ioo mineral oil and an aqueous soluble salt of beta naphthol 3: 6 disulpho acid.

7. In the treatment of textile fiber, the step which comprises treating the fiber with a soluble oil and an aqueous soluble salt of a sulpho acid of an aromatic hydroxy compound.

8. In the treatment of textile fiber, the step i which comprises treating the fiber with a s01- uble olive oil and an aqueous soluble salt of a sulpho acid of an aromatic hydroxy compound.

9. In the treatment of silk fiber, the step which comprises treating the fiber with a soluble oil and an aqueous soluble salt of a sulpho acid of an aromatic hydroxy compound.

10. In the treatment of silk fiber, the step which comprises treating the fiber with a soluble olive oil and an aqueous soluble salt of a sulpho acid of an aromatic hydroxy compound.

11. In the treatment of textile fiber, the

step which comprises treating the fiber with .a soluble mineral oil and an aqueous soluble salt of a sulpho acid of an aromatic hydroxy compound.

12. In the treatment of silk fiber, the step which comprises treating'the fiber with a soluble mineral oil and an aqueousv soluble salt of a sulpho acid of an aromatic hydroxy com pound.

13. In the treatment of textile fiber, the step which comprises treating the fiber with soluble mineral oil and an aqueous soluble salt of beta naphthol 3:6 disulpho acid.
